Our view is that the ethylene pathway is likely to be the most
achievable of the gas upgrading options for smaller scale gasification
(1-5 tonnes/hr feed rates). Produced as a co-product through a dedicated
retort with depleted exhaust gases from this used to fuel a generator.
Ethylene is relatively easy to form from CO & H2 as the catalytic retort
needed operates at very modest temperatures and pressures (300oC &
150psi). The ethylene produced can then be compressed and transported as
for LPG. It could be added to existing reticulated natural gas lines,
used directly as a transport fuel or as a feed stock for ethanol &/or
plastics manufacture. The ultimate in recycling, generating virgin
material from used. When we are over the current speed bumps on our
journey we might have a crack at it (excuse the pun).

DD I like this approach. Ethylene has the fossil fuel world buzzing here in
Ohio because they found a lot of natural gas liquids in the overlap zone
of the Utica Shale. ( The overlap zone between the oil rich shale to the
west and the gas rich shale to the east.) Butane and Propane, often found with
the Ethylene is also in real demand as a chemical feedstock and might be
produced in similar fashion. Other places around the world were not blessed
with such natural resources and might really benefit from creating their
own.
